Abstract
A process for the preparation of bromoalkyl esters and vicinal glycol esters which comprises thermally decomposing at temperatures of from 100.degree. C. to 200.degree. C. a bis(2-bromoalkyl)tellurium dicarboxylate compound of the formula ##STR1## wherein at least one R is hydrogen or R is a methyl group and R' is hydrogen or an alkyl group having 1 to 3 carbon atoms in the presence of an aliphatic monocarboxylic acid selected from formic, acetic, propionic or butyric acid employed as solvent and to facilitate solvolysis in the reaction to give in addition to the bromoalkyl ester, the vicinal glycol ester. An inert acetonitrile solvent may be employed alone to give predominately the bromoalkyl ester or an admixture with the acid may be employed. Oxygen is preferably employed with the carboxylic acid solvent to provide an increase in the mole ratio of vicinal glycol ester to the bromoalkyl ester produced.
